S&T BANCORP, INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


NOTE 1. BASIS OF PRESENTATION
Principles of Consolidation
The interim Consolidated Financial Statements include the accounts of S&T Bancorp, Inc., or S&T, and its wholly owned subsidiaries. All significant intercompany transactions have been eliminated in consolidation. Investments of 20 percent to 50 percent of the outstanding common stock of investees are accounted for using the equity method of accounting.
Basis of Presentation
The accompanying unaudited interim Consolidated Financial Statements of S&T have been prepared in accordance with generally accepted accounting principles, or GAAP, in the United States for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with our annual report on Form 10-K for the year ended December 31, 2014, filed with the Securities and Exchange Commission, or SEC, on February 20, 2015. In the opinion of management, the accompanying interim financial information reflects all adjustments, including normal recurring adjustments, necessary to present fairly our financial position and the results of operations for each of the interim periods presented. Results of operations for interim periods are not necessarily indicative of the results of operations that may be expected for a full year or any future period.
Reclassification
Certain amounts in the prior periods’ financial statements and footnotes have been reclassified to conform to the current period’s presentation. The reclassifications had no significant effect on our results of operations or financial condition.
Use of Estimates
The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates.

Recently Adopted Accounting Standards Updates, or ASU
Repurchase-To-Maturity Transactions, Repurchase Financings, and Disclosures
In June 2014, the Financial Accounting Standards Board, or FASB, issued ASU No. 2014-11, Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures which introduces two accounting changes to the Transfers and Servicing guidance (Topic 860). Repurchase-to-maturity transactions will be accounted for as secured borrowing transactions on the balance sheet and for repurchase financing arrangements, an entity will account separately for a transfer of a financial asset executed contemporaneously with a repurchase agreement with the same counterparty. This will also generally result in secured borrowing accounting for the repurchase agreement. With respect to disclosures, a transferor is required to disclose information about transactions accounted for as a sale in which the transferor retains substantially all of the exposure to the economic return on the transferred financial assets through an agreement with the transferee. Additionally, new disclosures are required for repurchase agreements, securities lending transactions, and repurchase-to-maturity transactions that are accounted for as secured borrowings. The new disclosure for transactions accounted for as secured borrowings is required for interim periods beginning after March 15, 2015. These new disclosures are included in Note 9. Borrowings. The adoption of this ASU had no impact on our results of operations or financial position.

Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity
In April 2014, the FASB issued ASU No. 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity, which changes the criteria for determining which disposals can be presented as discontinued operations and modifies related disclosure requirements. The guidance applies to all entities that dispose of components. It will significantly change current practices for assessing discontinued operations and affect an entity’s income and earnings per share from continuing operations. An entity is required to reclassify assets and liabilities of a discontinued operation that are classified as held for sale or disposed of in the current period for all comparative periods presented. The ASU requires that an entity present in the statement of cash flows or disclose in a note either total operating and investing cash flows for discontinued operations, or depreciation, amortization, capital expenditures and significant operating and investing noncash items related to

NOTE 1. BASIS OF PRESENTATION - continued

discontinued operations. Additional disclosures are required when an entity retains significant continuing involvement with a discontinued operation after its disposal, including the amount of cash flows to and from a discontinued operation. The new standard applies prospectively after the effective date of December 15, 2014, and early adoption was permitted. The adoption of this ASU had no impact on our results of operations or financial position.
Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure
In January 2014, the FASB issued ASU No. 2014-04, Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure. The ASU clarifies that an in substance repossession or foreclosure has occurred and a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure or the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure. Interim and annual disclosure is required of both the amount of foreclosed residential real estate property held by the creditor and the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure. The new standard is effective using either the modified retrospective transition method or a prospective transition method for fiscal years and interim periods within those years, beginning after December 15, 2014, and early adoption was permitted. The adoption of this ASU had no impact on our results of operations or financial position.
Accounting for Investments in Qualified Affordable Housing Projects
In January 2014, the FASB issued ASU No. 2014-01, Accounting for Investments in Qualified Affordable Housing Projects. The ASU permits reporting entities to make an accounting policy election to account for investments in qualified affordable housing projects using the proportional amortization method if certain conditions are met. The proportional amortization method permits the amortization of the initial cost of the investment in proportion to the tax credits and other tax benefits received, and recognizes the net investment performance in the income statement as a component of income tax expense (benefit). The new standard is effective retrospectively for fiscal years and interim periods within those years, beginning after December 15, 2014, and early adoption was permitted. This ASU did not have a material impact on our results of operations or financial position. We did not adopt the proportional amortization method. Refer to Note 14 for additional disclosure.
Recently Issued Accounting Standards Updates not yet Adopted
Intangibles – Goodwill and Other – Internal-Use Software: Customer's Accounting for Fees Paid in a Cloud Computing Arrangement
In April 2015, the FASB issued ASU No. 2015-05, Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40): Customer's Accounting for Fees Paid in a Cloud Computing Arrangement. The main provisions of ASU 2015-05 provide a basis for evaluating whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, then the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, then the arrangement should be accounted for as a service contract.

Interest – Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs
In April 2015, the FASB issued ASU No. 2015-03, Interest – Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. The amendments in this ASU require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The standard is required to be adopted by public business entities in annual periods beginning on or after December 15, 2016. We do not expect that this ASU will have a material impact on our results of operations or financial position.

Consolidation: Amendments to the Consolidation Analysis
In April 2015, the FASB issued ASU No. 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis. The amendments in this ASU affect reporting entities that are required to evaluate whether they should consolidate certain legal entities. All legal entities are subject to reevaluation under the revised consolidation model. Specifically, the amendments: 1) Modify the evaluation of whether limited partnerships and similar legal entities are variable interest entities (VIEs) or voting interest entities, 2) Eliminate the presumption that a general partner should consolidate a limited partnership, 3) Affect the consolidation analysis of reporting entities that are involved with VIEs, particularly those that have fee arrangements and related party relationships, 4) Provide a scope exception from consolidation guidance for reporting entities with interests in legal entities that are required to comply with or operate in accordance with requirements that are similar to those in Rule 2A-7 of the Investment Company Act of 1940 for registered money market funds. The amendments in this ASU are effective for public business entities for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015. We are currently evaluating the impact that these amendments may have on our consolidated financial statements. We do not expect that this ASU will have a material impact on our results of operations or financial position.
Income Statement – Extraordinary and Unusual Items: Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary
In January 2015, the FASB issued ASU No. 2015-01, Income Statement – Extraordinary and Unusual Items (Subtopic 225-20): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary. The amendments in this ASU eliminate from GAAP the concept of extraordinary items and eliminate the requirements for reporting entities to consider whether an underlying event or transaction is extraordinary. The presentation and disclosure guidance for items that are unusual in nature or occur infrequently will be retained and will be expanded to include items that are both unusual in nature and infrequently occurring. The standard is required to be adopted by public business entities in annual periods beginning on or after December 15, 2015. We do not expect that this ASU will have a material impact on our results of operations or financial position.

NOTE 2. BUSINESS COMBINATIONS


On March 4, 2015, we completed the acquisition of 100 percent of the voting shares of Integrity Bancshares, Inc., or Integrity, located in Camp Hill, Pennsylvania, in a tax-free reorganization transaction structured as a merger of Integrity with and into S&T, with S&T being the surviving entity. As a result of the Integrity merger, or the Merger, Integrity Bank, the wholly owned subsidiary bank of Integrity, became a separate wholly owned subsidiary bank of S&T. The merger of Integrity Bank into S&T Bank, with S&T Bank surviving the merger, and related system conversion occurred on May 8, 2015.
Integrity shareholders were entitled to elect to receive for each share of Integrity common stock either $52.50 in cash or 2.0627 shares of S&T common stock subject to allocation and proration procedures in the merger agreement. The total purchase price was approximately $172.0 million which included $29.5 million of cash and 4,933,115 S&T common shares at a fair value of $28.88 per share. The fair value of $28.88 per share of S&T common stock was based on the March 4, 2015 closing price.
The Merger was accounted for under the acquisition method of accounting and our consolidated financial statements include all Integrity Bank transactions from March 4, 2015, until it was merged into S&T Bank on May 8, 2015. The assets acquired and liabilities assumed were recorded at their respective fair values and represent management’s estimates based on available information. During the three months ended June 30, 2015, an additional $0.6 million of purchase accounting adjustments were recognized that increased goodwill. The change to goodwill primarily related to a fair value adjustment made on land acquired in the Merger where we own a branch office.
Goodwill of $115.4 million was calculated as the excess of the consideration exchanged over the fair value of the identifiable net assets acquired. The goodwill arising from the Merger consists largely of the synergies and economies of scale expected from combining the operations of S&T and Integrity. All of the goodwill was assigned to our Community Banking segment. The goodwill recognized will not be deductible for tax purposes.

Loans acquired in the Merger were recorded at fair value with no carryover of the related allowance for loan losses. Determining the fair value of the loans involves estimating the amount and timing of principal and interest cash flows expected to be collected on the loans and discounting those cash flows at a market rate of interest. Loans acquired with evidence of credit quality deterioration were evaluated and not considered to be significant. The fair value of the loans acquired was $788.7 million net of a $14.8 million discount. The discount may be accreted to interest income over the remaining contractual life of the loans. Acquired loans included $331.6 million of commercial real estate, or CRE, $184.2 million of commercial and

Direct costs related to the Merger were expensed as incurred. During the six months ended June 30, 2015, we recognized $3.2 million of merger related expenses, including $1.3 million for data processing contract termination and system conversion costs, $1.2 million in legal and professional expenses, $0.4 million in severance payments and $0.3 million in other expenses.

NOTE 4. FAIR VALUE MEASUREMENT

We use fair value measurements when recording and disclosing certain financial assets and liabilities. Securities available-for-sale, trading assets and derivatives are recorded at fair value on a recurring basis. Additionally, from time to time, we may be required to record other assets at fair value on a nonrecurring basis, such as loans held for sale, impaired loans, other real estate owned, or OREO, mortgage servicing rights, or MSRs, and certain other assets.
Fair value is the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants at the measurement date. An orderly transaction is a transaction that assumes exposure to the market for a period prior to the measurement date to allow for marketing activities that are usual and customary for transactions involving such assets or liabilities; it is not a forced transaction. In determining fair value, we use various valuation approaches, including market, income and cost approaches. The fair value standard establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing an asset or liability, which is developed, based on market data we have obtained from independent sources. Unobservable inputs reflect our estimate of assumptions that market participants would use in pricing an asset or liability, which are developed based on the best information available in the circumstances.
The fair value hierarchy gives the highest priority to unadjusted quoted market prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement). The fair value hierarchy is broken down into three levels based on the reliability of inputs as follows:
Level 1: valuation is based upon unadjusted quoted market prices for identical instruments traded in active markets.
Level 2: valuation is based upon quoted market prices for similar instruments traded in active markets, quoted market prices for identical or similar instruments traded in markets that are not active and model-based valuation techniques for which all significant assumptions are observable in the market or can be corroborated by market data.
Level 3: valuation is derived from other valuation methodologies, including discounted cash flow models and similar techniques that use significant assumptions not observable in the market. These unobservable assumptions reflect estimates of assumptions that market participants would use in determining fair value.
A financial instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. Our policy is to recognize transfers between any of the fair value hierarchy levels at the end of the reporting period in which the transfer occurred.
The following are descriptions of the valuation methodologies that we use for financial instruments recorded at fair value on either a recurring or nonrecurring basis.
Recurring Basis
Securities Available-for-Sale
Securities available-for-sale include both debt and marketable equity securities. We obtain fair values for debt securities from a third-party pricing service which utilizes several sources for valuing fixed-income securities. We validate prices received from our pricing service through comparison to a secondary pricing service and broker quotes. We review the methodologies of the pricing service which provides us with a sufficient understanding of the valuation models, assumptions, inputs and pricing to reasonably measure the fair value of our debt securities. The market valuation sources for debt securities include observable inputs rather than significant unobservable inputs and are classified as Level 2. The service provider utilizes pricing models that vary by asset class and include available trade, bid and other market information. Generally, the methodologies include broker quotes, proprietary models and vast descriptive terms and conditions databases, as well as extensive quality control programs.
Marketable equity securities that have an active, quotable market are classified as Level 1. Marketable equity securities that are quotable, but are thinly traded or inactive, are classified as Level 2. Marketable equity securities that are not readily traded and do not have a quotable market are classified as Level 3.
Trading Assets
We use quoted market prices to determine the fair value of our trading assets. Our trading assets are held in a Rabbi Trust under a deferred compensation plan and are invested in readily quoted mutual funds. Accordingly, these assets are classified as Level 1.

NOTE 4. FAIR VALUE MEASUREMENTS – continued

Derivative Financial Instruments
We use derivative instruments including interest rate swaps for commercial loans with our customers, interest rate lock commitments and the sale of mortgage loans in the secondary market. We calculate the fair value for derivatives using widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each derivative. Each valuation considers the contractual terms of the derivative, including the period to maturity, and uses observable market based inputs, such as interest rate curves and implied volatilities. Accordingly, derivatives are classified as Level 2. We incorporate credit valuation adjustments into the valuation models to appropriately reflect both our own nonperformance risk and the respective counterparties' nonperformance risk in calculating fair value measurements. In adjusting the fair value of our derivative contracts for the effect of nonperformance risk, we have considered the impact of netting any applicable credit enhancements and collateral postings.
Nonrecurring Basis
Loans Held for Sale
Loans held for sale consist of 1-4 family residential loans originated for sale in the secondary market and, from time to time, certain loans transferred from the loan portfolio to loans held for sale, all of which are carried at the lower of cost or fair value. The fair value of 1-4 family residential loans is based on the principal or most advantageous market currently offered for similar loans using observable market data. The fair value of the loans transferred from the loan portfolio is based on the amounts offered for these loans in currently pending sales transactions. Loans held for sale carried at fair value are classified as Level 3.
Impaired Loans
Impaired loans are carried at the lower of carrying value or fair value. Fair value is determined as the recorded investment balance less any specific reserve. We establish a specific reserve based on the following three impairment methods: 1) the present value of expected future cash flows discounted at the loan’s original effective interest rate, 2) the loan’s observable market price or 3) the fair value of the collateral less estimated selling costs when the loan is collateral dependent and we expect to liquidate the collateral. However, if repayment is expected to come from the operation of the collateral, rather than liquidation, then we do not consider estimated selling costs in determining the fair value of the collateral. Collateral values are generally based upon appraisals by approved, independent state certified appraisers. Appraisals may be discounted based on our historical knowledge, changes in market conditions from the time of appraisal or our knowledge of the borrower and the borrower’s business. Impaired loans carried at fair value are classified as Level 3.
OREO and Other Repossessed Assets
OREO and other repossessed assets obtained in partial or total satisfaction of a loan are recorded at the lower of recorded investment in the loan or fair value less cost to sell. Subsequent to foreclosure, these assets are carried at the lower of the amount recorded at acquisition date or fair value less cost to sell. Accordingly, it may be necessary to record nonrecurring fair value adjustments. Fair value, when recorded, is generally based upon appraisals by approved, independent state certified appraisers. Like impaired loans, appraisals on OREO may be discounted based on our historical knowledge, changes in market conditions from the time of appraisal or other information available to us. OREO and other repossessed assets carried at fair value are classified as Level 3.
Mortgage Servicing Rights
The fair value of MSRs is determined by calculating the present value of estimated future net servicing cash flows, considering expected mortgage loan prepayment rates, discount rates, servicing costs and other economic factors, which are determined based on current market conditions. The expected rate of mortgage loan prepayments is the most significant factor driving the value of MSRs. MSRs are considered impaired if the carrying value exceeds fair value. The valuation model includes significant unobservable inputs; therefore, MSRs are classified as Level 3.

NOTE 4. FAIR VALUE MEASUREMENTS – continued

Financial Instruments
In addition to financial instruments recorded at fair value in our financial statements, fair value accounting guidance requires disclosure of the fair value of all of an entity’s assets and liabilities that are considered financial instruments. The majority of our assets and liabilities are considered financial instruments. Many of these instruments lack an available trading market as characterized by a willing buyer and willing seller engaged in an exchange transaction. Also, it is our general practice and intent to hold our financial instruments to maturity and to not engage in trading or sales activities with respect to such financial instruments. For fair value disclosure purposes, we substantially utilize the fair value measurement criteria as required and explained above. In cases where quoted fair values are not available, we use present value methods to determine the fair value of our financial instruments.
Cash and Cash Equivalents
The carrying amounts reported in the Consolidated Balance Sheets for cash and due from banks, including interest-bearing deposits, approximate fair value.
Loans
The fair value of variable rate performing loans that may reprice frequently at short-term market rates is based on carrying values adjusted for credit risk. The fair value of variable rate performing loans that reprice at intervals of one year or longer, such as adjustable rate mortgage products, is estimated using discounted cash flow analyses that utilize interest rates currently being offered for similar loans and adjusted for credit risk. The fair value of fixed rate performing loans is estimated using a discounted cash flow analysis that utilizes interest rates currently being offered for similar loans and adjusted for credit risk. The fair value of impaired nonperforming loans is based on their carrying values less any specific reserve. The carrying amount of accrued interest approximates fair value.
Bank Owned Life Insurance
Fair value approximates net cash surrender value of bank owned life insurance.
Federal Home Loan Bank, or FHLB, and Other Restricted Stock
It is not practical to determine the fair value of our FHLB and other restricted stock due to the restrictions placed on the transferability of these stocks; therefore, it is presented at carrying value.
Deposits
The fair values disclosed for deposits without defined maturities (e.g., noninterest and interest-bearing demand, money market and savings accounts) are by definition equal to the amounts payable on demand. The carrying amounts for variable rate, fixed-term time deposits approximate their fair values. Estimated fair values for fixed rate and other time deposits are based on discounted cash flow analysis using interest rates currently offered for time deposits with similar terms. The carrying amount of accrued interest approximates fair value.
Short-Term Borrowings
The carrying amounts of securities sold under repurchase agreements and other short-term borrowings approximate their fair values.
Long-Term Borrowings
The fair values disclosed for fixed rate long-term borrowings are determined by discounting their contractual cash flows using current interest rates for long-term borrowings of similar remaining maturities. The carrying amounts of variable rate long-term borrowings approximate their fair values.
Junior Subordinated Debt Securities
The variable rate junior subordinated debt securities reprice quarterly; therefore, the fair values approximate the carrying values.

Loan Commitments and Standby Letters of Credit
Off-balance sheet financial instruments consist of commitments to extend credit and letters of credit. Except for interest rate lock commitments, estimates of the fair value of these off-balance sheet items are not made because of the short-term nature of these arrangements and the credit standing of the counterparties.
Other
Estimates of fair value are not made for items that are not defined as financial instruments, including such items as our core deposit intangibles and the value of our trust operations.
The following tables present our assets and liabilities that are measured at fair value on a recurring basis by fair value hierarchy level at June 30, 2015 and December 31, 2014. Due to limited trading volume, we transferred marketable equity securities with a fair value of $0.2 million from Level 1 to Level 2 during the six month period ended June 30, 2015. There were no other transfers between Level 1 and Level 2 for items measured at fair value on a recurring basis during the periods presented.

We classify financial instruments as Level 3 when valuation models are used because significant inputs are not observable in the market. We had no assets or liabilities measured at fair value on a recurring basis for which we have utilized Level 3 inputs to determine the fair value at either June 30, 2015 or December 31, 2014.
We may be required to measure certain assets and liabilities on a nonrecurring basis. Nonrecurring assets are recorded at the lower of cost or fair value in our financial statements. The following table presents our assets that were measured at fair value on a nonrecurring basis by the fair value hierarchy level at June 30, 2015 and December 31, 2014. There were no liabilities measured at fair value on a nonrecurring basis during these periods.

We do not believe any individual unrealized loss as of June 30, 2015 represents an other than temporary impairment. As of June 30, 2015, the unrealized losses on 25 debt securities were attributable to changes in interest rates and not related to the credit quality of these securities. All debt securities are determined to be investment grade and are paying principal and interest according to the contractual terms of the security. There were no unrealized losses on marketable equity securities as of June 30, 2015. We do not intend to sell and it is not more likely than not that we will be required to sell any of the securities, referenced in the table above, in an unrealized loss position before recovery of their amortized cost.

We attempt to limit our exposure to credit risk by diversifying our loan portfolio by segment, collateral and industry and actively managing concentrations. When concentrations exist in certain segments, we mitigate this risk by monitoring the relevant economic indicators and internal risk rating trends and through stress testing of the loans in these segments. Total commercial loans represented 76 percent of total portfolio loans at June 30, 2015 and 75 percent of total portfolio loans at December 31, 2014. Within our commercial portfolio, the CRE and commercial construction portfolios combined comprised $2.4 billion or 66 percent of total commercial loans and 50 percent of total portfolio loans at June 30, 2015 and 66 percent of total commercial loans and 49 percent of total portfolio loans at December 31, 2014. Of the $2.4 billion of CRE and commercial construction loans, $424.0 million were added as a result of the Merger. Further segmentation of the CRE and commercial construction portfolios by industry and collateral type reveal no concentration in excess of 7.0 percent of total loans at June 30, 2015 and December 31, 2014.
Our market area includes Pennsylvania and the contiguous states of Ohio, West Virginia, New York and Maryland. The majority of our commercial and consumer loans are made to businesses and individuals in this market area resulting in a geographic concentration. We believe our knowledge and familiarity with customers and conditions locally outweighs this geographic concentration risk. The conditions of the local and regional economies are monitored closely through publicly available data as well as information supplied by our customers. Management believes underwriting guidelines, active monitoring of economic conditions and ongoing review by credit administration mitigates the concentration risk present in the loan portfolio. Our CRE and commercial construction portfolios had out of market exposure of 6.3 percent of the combined portfolio and 3.1 percent of total loans at June 30, 2015 and 8.0 percent of the combined portfolio and 3.9 percent of total loans at December 31, 2014.
Troubled debt restructurings, or TDRs, are loans where we, for economic or legal reasons related to a borrower’s financial difficulties, grant a concession to the borrower that we would not otherwise grant. We strive to identify borrowers in financial difficulty early and work with them to modify the terms before their loan reaches nonaccrual status. These modified terms generally include extensions of maturity dates at a stated interest rate lower than the current market rate for a new loan with similar risk characteristics, reductions in contractual interest rates or principal deferment. While unusual, there may be instances of principal forgiveness. These modifications are generally for longer term periods that would not be considered insignificant. Additionally, we classify loans where the debt obligation has been discharged through a Chapter 7 Bankruptcy and not reaffirmed as TDRs.
We individually evaluate all substandard commercial loans that have experienced a forbearance or change in terms agreement, as well as all substandard consumer and residential mortgage loans that entered into an agreement to modify their existing loan to determine if they should be designated as TDRs. All TDRs are considered to be impaired loans and will be reported as impaired loans for the remaining life of the loan, unless the restructuring agreement specifies an interest rate equal to or greater than the rate that would be accepted at the time of the restructuring for a new loan with comparable risk and it is fully expected that the remaining principal and interest will be collected according to the restructured agreement. Further, all

NOTE 6. LOANS AND LOANS HELD FOR SALE - continued

impaired loans are reported as nonaccrual loans unless the loan is a TDR that has met the requirements to be returned to accruing status. TDRs can be returned to accruing status if the ultimate collectability of all contractual amounts due, according to the restructured agreement, is not in doubt and there is a period of a minimum of six months of satisfactory payment performance by the borrower either immediately before or after the restructuring.

For the three months ended June 30, 2015, we modified four C&I loans totaling $5.5 million, four commercial construction loans totaling $1.3 million, one CRE loan totaling $0.8 million and two home equity loans totaling $0.2 million that were not considered to be TDRs. For the six months ended June 30, 2015 we modified six C&I loans totaling $5.7 million, four commercial construction loans totaling $1.3 million, three CRE loans totaling $1.0 million and two home equity loans totaling $0.2 million that were not considered to be TDRs. The modifications represented instances where there were insignificant delays in payment of three months or less or we concluded that no concession was granted. As of June 30, 2015 we have no commitments to lend additional funds on any TDRs.

NOTE 7. ALLOWANCE FOR LOAN LOSSES

We maintain an allowance for loan losses, or ALL, at a level determined to be adequate to absorb estimated probable credit losses inherent in the loan portfolio as of the balance sheet date. We develop and document a systematic ALL methodology based on the following portfolio segments: 1) CRE, 2) C&I, 3) Commercial Construction, 4) Consumer Real Estate and 5) Other Consumer.
The following are key risks within each portfolio segment:
CRE—Loans secured by commercial purpose real estate, including both owner occupied properties and investment properties, for various purposes such as hotels, strip malls and apartments. Operations of the individual projects as well as global cash flows of the debtors are the primary sources of repayment for these loans. The condition of the local economy is an important indicator of risk, but there are also more specific risks depending on the collateral type as well as the business prospects of the lessee, if the project is not owner occupied.
C&I—Loans made to operating companies or manufacturers for the purpose of production, operating capacity, accounts receivable, inventory or equipment financing. Cash flow from the operations of the company is the primary source of repayment for these loans. The condition of the local economy is an important indicator of risk, but there are also more specific risks depending on the industry of the company. Collateral for these types of loans often do not have sufficient value in a distressed or liquidation scenario to satisfy the outstanding debt.
Commercial Construction—Loans made to finance construction of buildings or other structures, as well as to finance the acquisition and development of raw land for various purposes. While the risk of these loans is generally confined to the construction period, if there are problems, the project may not be complete, and as such, may not provide sufficient cash flow on its own to service the debt or have sufficient value in a liquidation to cover the outstanding principal. The condition of the local economy is an important indicator of risk, but there are also more specific risks depending on the type of project and the experience and resources of the developer.
Consumer Real Estate—Loans secured by first and second liens such as home equity loans, home equity lines of credit and 1-4 family residences, including purchase money mortgages. The primary source of repayment for these loans is the income and assets of the borrower. The condition of the local economy, in particular the unemployment rate, is an important indicator of risk for this segment. The state of the local housing market can also have a significant impact on this segment because low demand and/or declining home values can limit the ability of borrowers to sell a property and satisfy the debt.
Other Consumer—Loans made to individuals that may be secured by assets other than 1-4 family residences, as well as unsecured loans. This segment includes auto loans, unsecured loans and lines and credit cards. The primary source of repayment for these loans is the income and assets of the borrower. The condition of the local economy, in particular the unemployment rate, is an important indicator of risk for this segment. The value of the collateral, if there is any, is less likely to be a source of repayment due to less certain collateral values.
We further assess risk within each portfolio segment by pooling loans with similar risk characteristics. For the commercial loan classes, the most important indicator of risk is the internally assigned risk rating, including pass, special mention and substandard. Consumer loans are pooled by type of collateral, lien position and loan to value, or LTV, ratio for Consumer Real Estate loans. Historical loss rates are applied to these loan pools to determine the reserve for loans collectively evaluated for impairment.
The ALL methodology for groups of loans collectively evaluated for impairment is comprised of both a quantitative and qualitative analysis. A key assumption in the quantitative component of the reserve is the loss emergence period, or LEP. The LEP is an estimate of the average amount of time from the point at which a loss is incurred on a loan to the point at which the loss is confirmed. In general, the LEP will be shorter in an economic slowdown or recession and longer during times of economic stability or growth, as customers are better able to delay loss confirmation after a potential loss event has occurred. 
Another key assumption is the look-back period, or LBP, which represents the historical data period utilized to calculate loss rates.
Management monitors various credit quality indicators for both the commercial and consumer loan portfolios, including delinquency, nonperforming status and changes in risk ratings on a monthly basis.

We continually monitor the commercial loan portfolio through an internal risk rating system. Loan risk ratings are assigned based upon the creditworthiness of the borrower and are reviewed on an ongoing basis according to our internal policies. Loans within the pass rating generally have a lower risk of loss than loans risk rated as special mention or substandard.
Our risk ratings are consistent with regulatory guidance and are as follows:
Pass—The loan is currently performing and is of high quality.
Special Mention—A special mention loan has potential weaknesses that warrant management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects or in the strength of our credit position at some future date. Economic and market conditions, beyond the borrower’s control, may in the future necessitate this classification.
Substandard—A substandard loan is not adequately protected by the net worth and/or paying capacity of the borrower or by the collateral pledged, if any. Substandard loans have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. These loans are characterized by the distinct possibility that we will sustain some loss if the deficiencies are not corrected.

We monitor the delinquent status of the consumer portfolio on a monthly basis. Loans are considered nonperforming when interest and principal are 90 days or more past due or management has determined that a material deterioration in the borrower’s financial condition exists. The risk of loss is generally highest for nonperforming loans.

We individually evaluate all substandard and nonaccrual commercial loans greater than $0.5 million for impairment. Loans are considered to be impaired when based upon current information and events it is probable that we will be unable to collect all principal and interest payments due according to the original contractual terms of the loan agreement. All TDRs will be reported as an impaired loan for the remaining life of the loan, unless the restructuring agreement specifies an interest rate equal to or greater than the rate that would be accepted at the time of the restructuring for a new loan with comparable risk and it is expected that the remaining principal and interest will be fully collected according to the restructured agreement. For all TDRs, regardless of size, as well as all other impaired loans, we conduct further analysis to determine the probable loss and assign a specific reserve to the loan if deemed appropriate.

NOTE 8. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

Interest Rate Swaps
In accordance with applicable accounting guidance for derivatives and hedging, all derivatives are recognized as either assets or liabilities on the balance sheet at fair value. Interest rate swaps are contracts in which a series of interest rate flows (fixed and variable) are exchanged over a prescribed period. The notional amounts on which the interest payments are based are not exchanged. These derivative positions relate to transactions in which we enter into an interest rate swap with a commercial customer while at the same time entering into an offsetting interest rate swap with another financial institution. In connection with each transaction, we agree to pay interest to the customer on a notional amount at a variable interest rate and receive interest from the customer on the same notional amount at a fixed rate. At the same time, we agree to pay another financial institution the same fixed interest rate on the same notional amount and receive the same variable interest rate on the same notional amount. The transaction allows our customer to effectively convert a variable rate loan to a fixed rate loan with us receiving a variable rate. These agreements could have floors or caps on the contracted interest rates.
Pursuant to our agreements with various financial institutions, we may receive collateral or may be required to post collateral based upon mark-to-market positions. Beyond unsecured threshold levels, collateral in the form of cash or securities may be made available to counterparties of interest rate swap transactions. Based upon our current positions and related future collateral requirements relating to them, we believe any effect on our cash flow or liquidity position to be immaterial.
Derivatives contain an element of credit risk, including the possibility that we will incur a loss because a counterparty, which may be a financial institution or a customer, fails to meet its contractual obligations. All derivative contracts with financial institutions may be executed only with counterparties approved by our Asset and Liability Committee and derivatives with customers may only be executed with customers within credit exposure limits approved by our Senior Loan Committee. Interest rate swaps are considered derivatives, but are not accounted for using hedge accounting. As such, changes in the estimated fair value of the derivatives are recorded in current earnings and included in other noninterest income in the Consolidated Statements of Comprehensive Income.
Interest Rate Lock Commitments and Forward Sale Contracts
In the normal course of business, we sell originated mortgage loans into the secondary mortgage loan market. We also offer interest rate lock commitments to potential borrowers. The commitments are generally for 60 days and guarantee a specified interest rate for a loan if underwriting standards are met, but the commitment does not obligate the potential borrower to close on the loan. Accordingly, some commitments expire prior to becoming loans. We may encounter pricing risks if interest rates increase significantly before the loan can be closed and sold. We may utilize forward sale contracts in order to mitigate this pricing risk. Whenever a customer desires these products, a mortgage originator quotes a secondary market rate guaranteed for that day by the investor. The rate lock is executed between the mortgagee and us and in turn a forward sale contract may be executed between us and the investor. Both the interest rate lock commitment and the corresponding forward sale contract for each customer are considered derivatives, but are not accounted for using hedge accounting. As such, changes in the estimated fair value of the derivatives during the commitment period are recorded in current earnings and included in mortgage banking in the Consolidated Statements of Comprehensive Income.

NOTE 9. BORROWINGS

Short-term borrowings are for terms under one year and were comprised of retail repurchase agreements, or REPOs, and FHLB advances. FHLB advances are for various terms and are secured by a blanket lien on residential mortgages and other real estate secured loans. All REPOs are overnight short-term investments and are not insured by the Federal Deposit Insurance Corporation, or FDIC. Securities pledged as collateral under these REPO financing arrangements cannot be sold or repledged by the secured party and are therefore accounted for as a secured borrowing. Mortgage backed securities with a total carrying value of $50.5 million at June 30, 2015 and $35.6 million at December 31, 2014 were pledged as collateral for these secured transactions. The pledged securities are held in safekeeping at the Federal Reserve. Due to the overnight short-term nature of REPOs, potential risk due to a decline in the value of the pledged collateral is low. Collateral pledging requirements with REPOs are monitored daily.
Long-term borrowings are for original terms greater than one year and were comprised of FHLB advances, a capital lease and junior subordinated debt securities. Long-term FHLB advances are secured by the same loans as short-term borrowings. We had total long-term borrowings outstanding of $15.0 million at a fixed rate and $148.8 million at a variable rate at June 30, 2015, excluding our capital lease of $0.2 million. On March 5, 2015, we paid off $8.5 million and on June 18, 2015, we paid off the remaining $5.0 million of the $13.5 million junior subordinated debt assumed in the Merger.

We had total borrowings at June 30, 2015 and December 31, 2014 at the FHLB of Pittsburgh of $349.0 million and $309.3 million. The $349.0 million at June 30, 2015 consisted of $231.0 million in short-term borrowings and $118.0 million in long-term borrowings. Our maximum borrowing capacity with the FHLB of Pittsburgh was $1.9 billion at June 30, 2015. Our remaining borrowing availability is $1.4 billion. We utilized $0.5 billion of our borrowing capacity at June 30, 2015 consisting of $349.0 million for borrowings and $168.5 million for letters of credit to collateralize public funds.

NOTE 10. COMMITMENTS AND CONTINGENCIES


Commitments
In the normal course of business, we offer off-balance sheet credit arrangements to enable our customers to meet their financing objectives. These instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the financial statements. Our exposure to credit loss, in the event a customer does not satisfy the terms of the agreement, equals the contractual amount of the obligation less the value of any collateral. We apply the same credit policies in making commitments and standby letters of credit that are used for the underwriting of loans to customers. Commitments generally have fixed expiration dates, annual renewals or other termination clauses and may require payment of a fee. Because many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. Our allowance for unfunded commitments totaled $2.9 million at June 30, 2015 and $2.3 million at December 31, 2014. The allowance for unfunded commitments is included in other liabilities in the Consolidated Balance Sheets. The allowance for unfunded commitments is determined using a similar methodology as our ALL. The reserve is calculated by applying historical loss rates and qualitative adjustments to our unfunded commitments.
Estimates of the fair value of these off-balance sheet items were not made because of the short-term nature of these arrangements and the credit standing of the counterparties.
The following table sets forth the commitments and letters of credit as of the dates presented:

Litigation
In the normal course of business, we are subject to various legal and administrative proceedings and claims. While any type of litigation contains a level of uncertainty, we believe that the outcome of such proceedings or claims pending will not have a material adverse effect on our consolidated financial position or results of operations.

NOTE 12. EMPLOYEE BENEFITS

We maintain a defined benefit pension plan, or Plan, covering all employees hired prior to January 1, 2008. The benefits are based on years of service and the employee’s compensation for the highest five consecutive years in the last ten years. Contributions are intended to provide for benefits attributed to employee service to date and for those benefits expected to be earned in the future. At this time, we are not required to make a cash contribution to the Plan in 2015. The expected long-term rate of return on plan assets is 8.00 percent. Effective January 1, 2015, the Plan was amended to provide unmarried participants with the ability to name a beneficiary to receive a lump sum death benefit equal to 80% of the participant’s accrued benefit payable at normal retirement age, in the event the participant dies while employed by S&T.

NOTE 14. QUALIFIED AFFORDABLE HOUSING PROJECTS


We invest in affordable housing projects primarily to satisfy our Community Reinvestment Act requirements. As a limited partner in these operating partnerships, we receive tax credits and tax deductions for losses incurred by the underlying properties. We use the cost method to account for these partnerships. Our total investment in qualified affordable housing projects totaled $16.8 million at June 30, 2015 and $18.6 million at December 31, 2014. We had no open commitments to fund current or future investments in qualified affordable housing projects at June 30, 2015 or December 31, 2014. Amortization expense included in noninterest expense was $0.9 million and $1.9 million for the three and six months ended June 30, 2015 and $1.0 million and $2.0 million for the three and six months ended June 30, 2014. The amortization expense was offset by tax credits of $1.0 million and $2.0 million for the three and six months ended June 30, 2015 and $1.1 million and $2.2 million for the three and six months ended June 30, 2014 as a reduction to our federal tax provision.

Item 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS


Management’s Discussion and Analysis of Financial Condition and Results of Operations, or MD&A, represents an overview of our consolidated results of operations and financial condition and highlights material changes in our financial condition and results of operations at and for the three and six month periods ended June 30, 2015 and 2014. Our MD&A should be read in conjunction with our Consolidated Financial Statements and notes thereto. The results of operations reported in the accompanying Consolidated Financial Statements are not necessarily indicative of results to be expected in future periods.
Important Note Regarding Forward-Looking Statements
This quarterly report on Form 10-Q contains or incorporates statements that we believe are “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. These statements generally relate to our financial condition, results of operations, plans, objectives, future performance or business. They usually can be identified by the use of forward-looking language such as “will likely result,” “may,” “are expected to,” “is anticipated,” “estimate,” “forecast,” “projected,” “intends to” or other similar words. You should not place undue reliance on these statements, as they are subject to risks and uncertainties, including, but not limited to, those described in this Form 10-Q and our Annual Report on Form 10-K for the fiscal year ended December 31, 2014, which is on file with the Securities and Exchange Commission, or SEC. When considering these forward-looking statements, you should keep in mind these risks and uncertainties, as well as any cautionary statements we may make. Moreover, you should treat these statements as speaking only as of the date they are made and based only on information actually known to us at that time. We undertake no obligation to update publicly any forward-looking statements, whether as a result of new information, future events or otherwise.
These forward-looking statements are based on current expectations, estimates and projections about our business and beliefs and assumptions made by management. These Future Factors are not guarantees of our future performance and involve certain risks, uncertainties and assumptions, which are difficult to predict. Therefore, actual outcomes and results may differ materially from what is expressed or forecasted in these forward-looking statements.
Future Factors include:
•
credit losses;
•
cyber-security concerns, including an interruption or breach in the security of our information systems;
•
rapid technological developments and changes;
•
sensitivity to the interest rate environment including a prolonged period of low interest rates, a rapid increase in interest rates or a change in the shape of the yield curve;
•
a change in spreads on interest-earning assets and interest-bearing liabilities;
•
regulatory supervision and oversight, including Basel III required capital levels, and public policy changes, including environmental regulations;
•
legislation affecting the financial services industry as a whole, S&T, in particular, including the effects of the Dodd-Frank Act;
•
the outcome of pending and future litigation and governmental proceedings;
•
increasing price and product/service competition, including new entrants;
•
the ability to continue to introduce competitive new products and services on a timely, cost-effective basis;
•
managing our internal growth and acquisitions, particularly our recent acquisition of Integrity Bancshares, Inc., or Integrity;
•
the possibility that the anticipated benefits from the recent Integrity acquisition and any other future acquisitions cannot be fully realized in a timely manner or at all, or that integrating the operations of Integrity or future acquired operations will be more difficult, disruptive or costly than anticipated;
•
containing costs and expenses;
•
reliance on significant customer relationships;
•
general economic or business conditions, either nationally or regionally in western Pennsylvania and our other market areas, may be less favorable than expected, resulting in among other things, a reduced demand for credit and other services;
•
deterioration of the housing market and reduced demand for mortgages;
•
a deterioration in the overall macroeconomic conditions or the state of the banking industry that could warrant further analysis of the carrying value of goodwill and could result in an adjustment to its carrying value resulting in a non-cash charge to net income;

Item 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS - continued

•
a re-emergence of turbulence in significant portions of the global financial and real estate markets that could impact our performance, both directly, by affecting our revenues and the value of our assets and liabilities and indirectly, by affecting the economy generally; and
•
access to capital in the amounts, at the times and on the terms required to support our future businesses.
These are representative of the Future Factors that could affect the outcome of the forward-looking statements. In addition, such statements could be affected by general industry and market conditions and growth rates, general economic conditions, including interest rate fluctuations, and other Future Factors.
Critical Accounting Policies and Estimates
Our critical accounting policies involving the significant judgments and assumptions used in the preparation of the Consolidated Financial Statements as of June 30, 2015 have remained unchanged from the disclosures presented in our Annual Report on Form 10-K for the year ended December 31, 2014 under the section “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

Overview

We are a bank holding company headquartered in Indiana, Pennsylvania with assets of $6.1 billion at June 30, 2015.  We operate branch locations in 16 southwestern and southcentral Pennsylvania counties, and loan production offices in northeast and central Ohio and western New York. We provide a full range of financial services with retail and commercial banking products, cash management services, insurance and trust and brokerage services. Our common stock trades on the NASDAQ Global Select Market under the symbol “STBA.”
We earn revenue primarily from interest on loans and securities and fees charged for financial services provided to our customers. Offsetting these revenues are the cost of deposits and other funding sources, provision for loan losses and other operating costs such as salaries and employee benefits, data processing, occupancy and tax expense.
Our mission is to become the financial services provider of choice within the markets that we serve. We strive to do this by delivering exceptional service and value, one customer at a time. Our strategic plan focuses on organic growth, which includes growth within our current footprint and growth through market expansion. We also actively evaluate acquisition opportunities as another source of growth. Our strategic plan includes a collaborative model that combines expertise from all of our business segments and focuses on satisfying each customer’s individual financial objectives.
On March 4, 2015, we completed a merger with Integrity Bancshares, Inc., or the Merger, which expanded our geographic footprint into southcentral Pennsylvania with eight branches in Cumberland, Dauphin, Lancaster and York counties. The transaction was valued at $172.0 million and added total assets of $980.7 million, including $788.7 million in loans and $115.4 million of goodwill, and $722.3 million in deposits. Integrity Bank became a separate subsidiary of S&T upon completion of the Merger and was subsequently merged into S&T Bank on May 8, 2015. For a period of at least three years following the Merger, S&T Bank intends to operate bank branches in the markets that were previously served by Integrity using the name "Integrity Bank – A Division of S&T Bank".
During the six months ended June 30, 2015, we successfully executed on our growth strategy in our current footprint and by expanding into new markets. Our portfolio loans grew $929.8 million, or 24.0 percent, since December 31, 2014, primarily due to the increase in loans from the Merger. On March 23, 2015, we expanded our commercial banking operations by opening a loan production office in western New York.
Our focus continues to be on loan and deposit growth and implementing opportunities to increase fee income while maintaining a strong expense discipline. Additionally, with our recent expansion into new markets, we are focused on executing our strategy to successfully build our brand and grow our business in these markets.The low interest rate environment remains a challenge for our net interest income, but our organic growth will help to mitigate the impact.
Earnings Summary
Net income for the three months ended June 30, 2015 was $18.2 million, or $0.52 per diluted share, compared to $14.7 million, or $0.49 per diluted share, for the same period in 2014. Net income for the six months ended June 30, 2015 was $31.0 million, or $0.94 per diluted share, compared to $28.8 million, or $0.97 per diluted share, for the same period in 2014. The increase in net income was primarily due to an increase in net interest income and noninterest income, offset by higher provision for loan losses and noninterest expense. Integrity's results have been included in our financial statements since the consummation of the Merger on March 4, 2015. Our results included $0.9 million of merger related expenses for the three months ended June 30, 2015 and $3.2 million for the six months ended June 30, 2015.

Item 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS - continued

Net interest income increased $12.0 million, or 32.4 percent, for the second quarter of 2015 compared to the same period in 2014 and increased $16.6 million, or 22.9 percent, for the six months ended June 30, 2015. The increases were primarily due to the increase in average interest-earning assets of $1.2 billion and $896.4 million for the three and six months ended June 30, 2015 compared to the same periods in 2014. Net interest income was favorably impacted by accretion resulting from purchase accounting fair value adjustments of $2.7 million for the three months and six months ended June 30, 2015.
The provision for loan losses increased $3.2 million to $2.1 million for the three months ended June 30, 2015 and $4.1 million to $3.3 million for the six months ended June 30, 2015 compared to the same periods in 2014. We had net loan charge-offs in both the three and six months ended June 30, 2015 compared to net recoveries in the same periods in the prior year. Net loan charge-offs increased $2.4 million to $1.4 million for the three months ended June 30, 2015 and increased $3.5 million to $2.4 million for the six months ended June 30, 2015. This compares to net recoveries of $1.1 million and $1.2 million for the same periods in 2014.
Noninterest income increased $1.6 million for the three months ended June 30, 2015 and $2.3 million for the six months ended June 30, 2015 compared to the same periods in 2014. The increases in noninterest income were primarily due to higher income as a result of the Merger and higher mortgage banking income.
Total noninterest expense increased $5.3 million for the three months ended June 30, 2015 and $10.0 million for the six months ended June 30, 2015 compared to the same periods in 2014. The increases were primarily due to merger related expenses, higher operating expenses related to the addition of locations related to the Merger and higher salaries and employee benefit costs.
The provision for income taxes increased $1.6 million for the three months ended June 30, 2015 and increased $2.5 million for the six months ended June 30, 2015 as compared to the same periods in 2014. The increase to the tax provision was due to an increase in our annual projected tax rate for 2015 as a result of higher projected pretax income primarily related to the Merger.
Explanation of Use of Non-GAAP Financial Measures
In addition to the results of operations presented in accordance with generally accepted accounting principles, or GAAP, management uses, and this quarterly report contains or references, certain non-GAAP financial measures, such as net interest income on a fully taxable equivalent, or FTE, basis and operating revenue. Management believes these non-GAAP financial measures provide information useful to investors in understanding our underlying business, operational performance and performance trends as they facilitate comparisons with the performance of others in the financial services industry. Although management believes that these non-GAAP financial measures enhance investors’ understanding of our business and performance, these non-GAAP financial measures should not be considered an alternative to GAAP or considered to be more important than financial results determined in accordance with GAAP, nor are they necessarily comparable with non-GAAP measures which may be presented by other companies.
We believe the presentation of net interest income on a FTE basis ensures the comparability of net interest income arising from both taxable and tax-exempt sources and is consistent with industry practice. Interest income per the Consolidated Statements of Comprehensive Income is reconciled to net interest income adjusted to a FTE basis in the Net Interest Income section of the Results of Operations for the three and six months ended June 30, 2015 and 2014.
Operating revenue is the sum of net interest income and noninterest income less non-recurring income and expenses. In order to understand the significance of net interest income to our business and operating results, we believe it is appropriate to evaluate the significance of net interest income as a component of operating revenue.

Net Interest Income
Our principal source of revenue is net interest income. Net interest income represents the difference between the interest and fees earned on interest-earning assets and the interest paid on interest-bearing liabilities. Net interest income is affected by changes in the average balance of interest-earning assets and interest-bearing liabilities and changes in interest rates and spreads. Maintaining consistent spreads between interest-earning assets and interest-bearing liabilities is significant to our financial performance because net interest income comprised 78 percent of operating revenue (net interest income plus noninterest income, excluding security gains/losses and non-recurring income) for both the three and six months ended June 30, 2015 and 77 percent and 76 percent of operating revenue for the three and six months ended June 30, 2014. The level and mix of interest-earning assets and interest-bearing liabilities is managed by our Asset and Liability Committee, or ALCO, in order to mitigate interest rate and liquidity risks of the balance sheet. A variety of ALCO strategies were implemented, within prescribed ALCO risk parameters, to produce an acceptable level of net interest income.
The interest income on interest-earning assets and the net interest margin are presented on a FTE basis. The FTE basis adjusts for the tax benefit of income on certain tax-exempt loans and securities using the federal statutory tax rate of 35 percent for each period and the dividend-received deduction for equity securities. We believe this to be the preferred industry measurement of net interest income that provides a relevant comparison between taxable and non-taxable amounts.

Net interest income on a FTE basis increased $12.1 million, or 31.5 percent, for the three months ended June 30, 2015 and $16.8 million, or 22.3 percent, for the six months ended June 30, 2015 compared to the same periods in 2014. The net interest margin on a FTE basis increased 11 basis points for the three months ended June 30, 2015 and 4 basis points for the six months ended June 30, 2015 compared to the same periods of 2014. Net interest income was favorably impacted by accretion resulting from purchase accounting fair value adjustments of $2.7 million. This impacted net interest margin on a FTE basis by 21 basis points for the three months ended June 30, 2015 and 11 basis points for the six months ended June 30, 2015.
Interest income on a FTE basis increased $12.8 million, or 31.1 percent, to $54.1 million and $18.2 million, or 22.3 percent, to $99.4 million for the three and six months ended June 30, 2015 compared to the same periods in 2014. Average interest-earning assets increased $1.2 billion and $896.4 million for the three and six months ended June 30, 2015 compared to the same periods in 2014. The average interest-earning asset increases were primarily due to higher average loan balances of

$1.1 billion and $832.0 million, related to the Merger and organic growth as compared to the same periods in 2014. The rate earned on loans was favorably impacted by purchase accounting accretion of $2.0 million, or 18 basis points and 10 basis points for the three and six months ended June 30, 2015. Average interest-bearing deposits with banks decreased $23.5 million and $53.0 million for the three and six months ended June 30, 2015 compared to the same periods of 2014. Average investment securities increased $92.8 million and $111.6 million for the three and six months ended June 30, 2015. The $2.0 million loan purchase accounting accretion had a positive impact on the interest-earning asset rate of 16 basis points and nine basis points for the three and six months ended June 30, 2015. Overall, the FTE rate on interest-earning assets increased 10 basis points and five basis points compared to the same periods in 2014.
Interest expense increased $0.8 million and $1.4 million for the three and six months ended June 30, 2015 compared to the same periods in 2014. The increase in interest expense was mainly driven by the Merger and organic growth of $823.8 million and $573.4 million in average interest-bearing deposits for the three and six months ended June 30, 2015 compared to the same periods in 2014. Average interest-bearing customer deposits, which excludes brokered deposits, increased $706.9 million and $479.8 million for the three and six months ended June 30, 2015 compared to the same periods in 2014. Average brokered deposits increased by $117.0 million and $93.6 million for the three and six months ended June 30, 2015 compared to the same periods in 2014. Interest expense on average borrowings increased $0.2 million and $0.3 million for the three and six months ending June 30, 2015 compared to the same periods in 2014. The $0.7 million certificate of deposit purchase accounting accretion had a positive impact on the interest-bearing liability rate of seven basis points and four basis points for the three and six months ended June 30, 2015. Overall, the cost of interest-bearing liabilities decreased by two basis points and one basis point compared to the same periods in 2014.

Provision for Loan Losses
The provision for loan losses is the adjustment to the allowance for loan losses, or ALL, after considering loan charge-offs and recoveries to bring the ALL to a level determined to be appropriate in management's judgment to absorb probable losses inherent in the loan portfolio. The provision for loan losses increased $3.2 million to $2.1 million for the three months ended

June 30, 2015 and $4.1 million to $3.3 million for the six months ended June 30, 2015 compared to the same periods in 2014. We had net loan charge-offs in both the three and six months ended June 30, 2015 compared to net recoveries in the same periods in the prior year. Net loan charge-offs increased $2.4 million to $1.4 million for the three months ended June 30, 2015 and increased $3.5 million to $2.4 million for the six months ended June 30, 2015. This compares to net recoveries of $1.1 million and $1.2 million for the same periods in 2014.
Nonaccrual loans increased $4.2 million to $19.1 million at June 30, 2015 compared to $14.9 million at June 30, 2014. Total special mention and substandard commercial loans have increased $60.1 million over the last twelve months to $203.1 million at June 30, 2015, primarily related to the Merger. The ALL was 1.02 percent of total portfolio loans and 1.23 percent of total originated loans at June 30, 2015 compared to 1.25 percent and 1.29 percent at June 30, 2014. The decrease in the overall level of the reserve as a percentage to total portfolio loans is due to the Merger as the acquired loans were recorded at fair value. Refer to “Allowance for Loan Losses” in the MD&A of this report for additional information.

Noninterest income increased $1.6 million, or 13.7 percent, and $2.3 million, or 9.8 percent, to $13.4 million and $25.5 million for the three and six month periods ended June 30, 2015 compared to the same periods in 2014. The increases related primarily to higher mortgage banking fees, other noninterest income, services charges on deposit accounts and debit and credit card fees for both periods.
Mortgage banking income increased $0.5 million and $0.9 million for the three and six month periods ended June 30, 2015 compared to the same periods in 2014. The increase in mortgage banking income related to an increase in the volume of loans originated for sale in the secondary market, in part due to the Merger, and more favorable pricing on loan sales. During the six months ended June 30, 2015, we had $41.4 million in loan sales compared to $13.1 million during the same period in 2014.
The increases in other noninterest income of $0.5 million and $0.6 million for the three and six month periods ended June 30, 2015 related to higher interest rate swap fees from our commercial customers, letter of credit fees and bank owned life insurance, or BOLI, income. The increases in letter of credit fees and BOLI income were primarily related to the Merger. Service charges on deposit accounts increased $0.3 million and $0.4 million for the three and six month periods ended June 30, 2015 due to the Merger and fee increases in the second half of 2014. The increases in debit and credit card fees of $0.3 million and $0.5 million were primarily due to an increase in merchant revenue resulting from the timing of referral revenue and increased debit card usage.

Noninterest expense increased $5.3 million, or 17.5 percent, and $10.0 million, or 16.9 percent, to $35.4 million and $69.1 million for the three and six month periods ended June 30, 2015 compared to the same periods of 2014. The increases were due in part to $0.9 million and $3.2 million in merger related expenses and higher operating expenses due to the Merger.
The total merger related expenses for the six month period ended June 30, 2015 of $3.2 million included $1.3 million for data processing contract termination and conversion costs, $1.2 million in legal and professional expenses, $0.4 million in severance payments and $0.3 million in various other expenses.
Salaries and employee benefits expense increased $1.7 million and $3.1 million for the three and six months ended June 30, 2015 compared to the same periods in 2014, primarily due to additional employees, annual merit increases and higher pension and incentive expense. For the three and six months ended June 30, 2015, approximately $1.1 million and $1.9 million of the increase related to the addition of new employees resulting from the Merger. Annual merit increases resulted in $0.4 million of additional salary expense for the three month period ended and $0.8 million for the six month period ended June 30, 2015 compared to the same periods in the prior year. Pension expense increased $0.2 million for the three months ended and $0.4 million for the six months ended due to a change in actuarial assumptions used to calculate our pension liability. Incentive expense increased $0.5 million for the three months ended and $0.9 million for the six months ended June 30, 2015 due to a higher number of participants and strong performance in the first half of 2015.
Other noninterest expense increased $0.7 million and $0.9 million for the three and six months ended June 30, 2015 compared to the same periods in 2014. The increase related to higher loan collection expenses, data lines, travel, lodging and training all primarily related to the Merger.
Net occupancy expense increased $0.7 million and $1.1 million for the three and six months ended June 30, 2015 compared to the same periods in 2014 and furniture and equipment expense increased $0.3 million for both periods primarily due to the additional locations acquired as part of the Merger. Data processing increased $0.3 million and $0.6 million for the three and six months ended June 30, 2015, primarily due to an increased customer processing base due to the Merger. Other taxes increased $0.3 million and $0.5 million due to the Merger. Marketing expense increased $0.2 million and $0.4 million related to the Merger and the timing of various promotional programs.

Provision for Income Taxes
The provision for income taxes increased $1.6 million to $6.5 million for the three months ended June 30, 2015 and $2.5 million to $11.2 million for the six month period ended June 30, 2015 compared to a provision of $4.9 million and $8.6 million for the same periods in 2014. The increases to the provision for income taxes for the three and six month periods ended June 30, 2015 were primarily due to higher pretax income and an increase in our 2015 annual projected tax rate. The increase in our annual projected tax rate is due to higher projected pretax income for the year. The effective tax rate for the six months ended June 30, 2015 increased to 26.5 percent compared to 23.1 percent for the same period in 2014.
Financial Condition
June 30, 2015
Total assets increased $1.1 billion to $6.1 billion at June 30, 2015 compared to $5.0 billion at December 31, 2014. The increase was primarily a result of the Merger, which increased total assets $980.7 million, including adding $115.3 million of goodwill. Portfolio loans increased $929.8 million compared to December 31, 2014 primarily due to organic growth and the Merger, which added $788.7 million of loans. Our commercial loan portfolio increased by $746.8 million, or 25.8 percent, of which $608.2 million related to the Merger and our consumer loan portfolio increased by $183.0 million, or 18.7 percent, of which $180.5 million related to the Merger. Securities increased $26.4 million, or 4.1 percent, compared to December 31, 2014 due to normal purchase activity.
Our deposit base increased $950.6 million with total deposits of $4.9 billion at June 30, 2015 compared to $3.9 billion at December 31, 2014. The increase in deposits consisted of $722.3 million related to the Merger, $132.7 million of organic growth in customer deposits and $95.5 million of brokered deposits. Borrowings increased by $55.4 million to $441.1 million at June 30, 2015 compared to $385.7 million at December 31, 2014. Long-term borrowings increased $98.8 million during the second quarter of 2015 as a result of shifting $100.0 million of short-term borrowings to a long-term variable rate borrowing. Short-term borrowings decreased $59.0 million due to the shift to long-term borrowings offset by additional funding needed to support our asset growth. Total shareholders' equity increased by $162.8 million, or 26.8 percent, at June 30, 2015 compared to December 31, 2014. The increase was primarily related to the issuance of common stock for the Merger of $142.5 million and net income of $31.0 million, which was partially offset by dividends of $11.6 million.

We invest in various securities in order to maintain a source of liquidity, to satisfy various pledging requirements, increase net interest income and as a tool of the ALCO to reposition the balance sheet for interest rate risk purposes. Securities are subject to market risk that could negatively affect the level of liquidity available to us. Security purchases are subject to an investment policy approved annually by our Board of Directors and administered through ALCO and our treasury function. The securities portfolio increased $26.4 million from December 31, 2014 to June 30, 2015, primarily due to normal purchase activity. We acquired $11.5 million of securities through the Merger. During the three months ended June 30, 2015, we sold all of the acquired securities.
Management evaluates the securities portfolio for other than temporary impairment, or OTTI, on a quarterly basis. At June 30, 2015 our bond portfolio was in a net unrealized gain position of $8.7 million, compared to a net unrealized gain of $9.3 million at December 31, 2014. At June 30, 2015, total gross unrealized gains were $10.3 million offset by total gross unrealized losses of $1.6 million. At December 31, 2014, total gross unrealized gains were $11.2 million offset by gross unrealized losses of $1.8 million. Unrealized losses were not related to the underlying credit quality of the bond portfolio. All debt securities are

determined to be investment grade and are paying principal and interest according to the contractual terms of the securities. There were no unrealized losses on marketable equity securities as of June 30, 2015 and December 31, 2014. We do not intend to sell and it is not more likely than not that we will not be required to sell any of the securities in an unrealized loss position before recovery of their amortized cost. During the six months of 2015 and 2014 we did not record any OTTI. The performance of the debt and equity securities markets could generate impairments in future periods requiring realized losses to be reported.

Our loan portfolio represents our most significant source of interest income. The risk that borrowers will be unable to pay such obligations is inherent in the loan portfolio. Other conditions such as downturns in the borrower's industry or the overall economic climate can significantly impact the borrower’s ability to pay.
Total portfolio loans increased $929.7 million to $4.8 billion compared to $3.9 billion at December 31, 2014. The increase was primarily due to the addition of $788.7 million of loans from the Merger and $141.0 million of organic growth. The $788.7 million of loans related to the Merger consisted of $331.6 million of commercial real estate, or CRE, $184.2 million of commercial and industrial, or C&I, $92.4 million of commercial construction, $116.9 million of residential mortgage, $25.6 million of home equity, $36.1 million of installment and other consumer and $1.9 million of consumer construction.
Allowance for Loan Losses
We maintain an ALL at a level determined to be adequate to absorb estimated probable credit losses inherent within the loan portfolio as of the balance sheet date. Determination of an adequate ALL is inherently subjective and may be subject to significant changes from period to period. The methodology for determining the ALL has two main components: 1) evaluation and impairment tests of individual loans, and 2) impairment tests of certain groups of homogeneous loans with similar risk characteristics.
An inherent risk to the loan portfolio as a whole is the condition of the local economy. In addition, each loan segment carries with it risks specific to the segment. We develop and document a systematic ALL methodology based on the following portfolio segments: 1) CRE, 2) C&I, 3) Commercial Construction, 4) Consumer Real Estate and 5) Other Consumer. The following is a discussion of the key risks by portfolio segment that management assesses in preparing the ALL.
CRE loans are secured by commercial purpose real estate, including both owner occupied properties and investment properties for various purposes such as hotels, strip malls and apartments. Operations of the individual projects as well as global cash flows of the debtors are the primary sources of repayment for these loans. The condition of the local economy is an important indicator of risk, but there are also more specific risks depending on the collateral type as well as the business prospects of the lessee, if the project is not owner occupied.
C&I loans are made to operating companies or manufacturers for the purpose of production, operating capacity, accounts receivable, inventory or equipment financing. Cash flow from the operations of the company is the primary source of repayment for these loans. The condition of the local economy is an important indicator of risk, but there are also more specific

55

Item 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS - continued

risks depending on the industry of the company. Collateral for these types of loans often do not have sufficient value in a distressed or liquidation scenario to satisfy the outstanding debt.
Commercial construction loans are made to finance construction of buildings or other structures, as well as to finance the acquisition and development of raw land for various purposes. While the risk of these loans is generally confined to the construction period, if there are problems, the project may not be completed, and as such, may not provide sufficient cash flow on its own to service the debt or have sufficient value in a liquidation to cover the outstanding principal. The condition of the local economy is an important indicator of risk, but there are also more risks depending on the type of project and the experience and resources of the developer.
Consumer real estate loans are secured by first and second liens such as home equity loans, home equity lines of credit and 1-4 family residences, including purchase money mortgages. The primary source of repayment for these loans is the income and assets of the borrower. The condition of the local economy, in particular the unemployment rate, is an important indicator of risk for this segment. The state of the local housing markets can also have a significant impact on this segment because low demand and/or declining home values can limit the ability of borrowers to sell a property and satisfy the debt.
Other consumer loans are made to individuals and may be secured by assets other than 1-4 family residences, as well as unsecured loans. This segment includes auto loans, unsecured loans and lines and credit cards. The primary source of repayment for these loans is the income and assets of the borrower. The condition of the local economy, in particular the unemployment rate, is an important indicator of risk for this segment. The value of the collateral, if there is any, is less likely to be a source of repayment due to less certain collateral values.

The ALL was $48.8 million, or 1.02 percent of total portfolio loans and 1.23 percent of originated loans at June 30, 2015 compared to $47.9 million, or 1.24 percent of total portfolio loans and 1.27 percent of originated loans at December 31, 2014. The decrease in the ALL to total portfolio loans from December 31, 2014 to June 30, 2015 is due to the Merger. Acquired loans of $788.7 million were recorded at fair value with no carryover of the ALL. Credit deterioration on acquired loans incurred subsequent to the acquisition date will be recognized in the ALL through the provision. During the second quarter of 2015, one CRE impaired loan required a specific reserve of $0.6 million. Impaired loans increased $1.9 million from December 31, 2014. During 2015 there were $8.6 million of newly identified impaired loans which were partially offset by pay-downs. The reserve for loans collectively evaluated for impairment did not change significantly at June 30, 2015 compared to December 31, 2014.
Net loan charge-offs were $1.4 million and $2.4 million for the three months and six months ended June 30, 2015. Commercial special mention and substandard loans for the second quarter increased by $90.9 million to $203.1 million compared to $112.2 million at December 31, 2014 primarily related to the acquired loans which were recorded at fair value on the acquisition date.
We individually evaluate all substandard and nonaccrual commercial loans greater than $0.5 million for impairment. Loans are considered to be impaired when based upon current information and events it is probable that we will be unable to collect all principal and interest payments due according to the original contractual terms of the loan agreement. Our methodology for evaluating whether a loan is impaired includes risk-rating credits on an individual basis and consideration of the borrower’s overall financial condition, payment history and available cash resources. In measuring impairment, we primarily utilize fair market value of the collateral; however, we also use discounted cash flow when warranted.
Troubled debt restructurings, or TDRs, whether on accrual or nonaccrual status, are also classified as impaired loans. TDRs are loans where we, for economic or legal reasons related to a borrower’s financial difficulties, grant a concession to the borrower that we would not otherwise grant. These modified terms generally include extensions of maturity dates at a stated interest rate lower than the current market rate for a new loan with similar risk characteristics, reductions in contractual interest rates or principal deferment. While unusual there may be instances of principal forgiveness. Generally these concessions are for a period of at least six months. Additionally, we classify loans where the debt obligation has been discharged through a Chapter 7 Bankruptcy and not reaffirmed by the borrower as TDRs.
An accruing loan that is modified into a TDR can remain in accrual status if, based on a current well-documented credit analysis, collection of principal and interest in accordance with the modified terms is reasonably assured, and the borrower has demonstrated sustained historical repayment performance for a reasonable period before the modification. Additionally, TDRs can be returned to accruing status if the following criteria are met: 1) the ultimate collectability of all contractual amounts due, according to the restructured agreement, is not in doubt and 2) there is a period of a minimum of six months of satisfactory payment performance by the borrower either immediately before or after the restructuring. All TDRs will be reported as an impaired loan for the remaining life of the loan, unless the restructuring agreement specifies an interest rate equal to or greater than the rate that would be accepted at the time of the restructuring for a new loan with comparable risk and it is expected that the remaining principal and interest will be fully collected according to the restructured agreement. For all TDRs, regardless of size, as well as all other impaired loans, we conduct further analysis to determine the probable loss and assign a specific reserve to the loan if deemed appropriate. All impaired loans are reported as nonaccrual loans unless the loan is a TDR that has met the requirements noted above.
As an example, consider a substandard commercial construction loan that is currently 90 days past due where the loan is restructured to extend the maturity date for a period longer than would be considered an insignificant period of time. The post-modification interest rate given to the borrower is considered to be lower than the current market rate for new debt with similar risk and all other terms remain the same according to the original loan agreement. This loan will be considered a TDR as the borrower is experiencing financial difficulty and a concession has been granted due to the long extension, resulting in payment delay as well as the rate being lower than current market rate for new debt with similar risk. The loan will be reported as a nonaccrual TDR and an impaired loan. In addition, the loan could be charged down to the fair value of the collateral if a confirmed loss exists. If the loan subsequently performs, by means of making on-time principal and interest payments according to the newly restructured terms for a period of six months, and it is expected that all remaining principal and interest will be collected according to the terms of the restructured agreement, the loan will be returned to accrual status and reported as an accruing TDR. The loan will remain an impaired loan for the remaining life of the loan because the interest rate was not adjusted to be equal to or greater than the rate that would be accepted at the time of the restructuring for a new loan with comparable risk.
At June 30, 2015, TDR’s totaled $41.5 million, which was a decrease of $0.9 million from December 31, 2014. Of the total TDR’s for the six months ended June 30, 2015, $32.6 million, or 78.5 percent, were accruing while $8.9 million, or 21.5 percent, were nonaccrual.
The charge-off policy for commercial loans requires that loans and other obligations that are not collectible be promptly charged-off when the loss becomes probable, regardless of the delinquency status of the loan. We may elect to recognize a

57
Table of Contents

S&T BANCORP, INC. AND SUBSIDIARIES
Item 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS - continued

partial charge-off when management has determined that the value of collateral is less than the remaining investment in the loan. A loan or obligation does not need to be charged-off, regardless of delinquency status, if (i) management has determined there exists sufficient collateral to protect the remaining loan balance and (ii) there exists a strategy to liquidate the collateral. Management may also consider a number of other factors to determine when a charge-off is appropriate. These factors may include, but are not limited to:
•
The status of a bankruptcy proceeding
•
The value of collateral and probability of successful liquidation; and/or
•
The status of adverse proceedings or litigation that may result in collection
Consumer unsecured loans and secured loans are evaluated for charge-off after the loan becomes 90 days past due. Unsecured loans are fully charged-off and secured loans are charged-off to the estimated fair value of the collateral less the cost to sell.
Our allowance for lending-related commitments is computed using a methodology similar to that used to determine the ALL. Amounts are added to the allowance for lending-related commitments by a charge to current earnings through noninterest expense. The reserve is calculated by applying historical loss rates and considering qualitative factors to unfunded commitments. The balance in the allowance for unfunded loan commitments was approximately $2.9 million at June 30, 2015 as compared to $2.3 million at December 31, 2014. The increase primarily relates to the Merger. The allowance for unfunded commitments is included in other liabilities in the Consolidated Balance Sheets.
Nonperforming assets consist of nonaccrual loans, nonaccrual TDRs and OREO. The following table summarizes nonperforming assets for the dates presented:

Our policy is to place loans in all categories in nonaccrual status when collection of interest or principal is doubtful, or generally when interest or principal payments are 90 days or more past due.
Nonperforming assets, or NPAs, increased by $7.3 million to $19.9 million at June 30, 2015 compared to $12.6 million at December 31, 2014. The increase in NPAs was primarily due to a $6.7 million increase in nonperforming loans and a $0.6 million increase in OREO acquired from the Merger. The increase in nonperforming loans was primarily due to the further

Deposits are our primary source of funds. We believe that our deposit base is stable and that we have the ability to attract new deposits, mitigating any funding dependency on other more volatile sources. Total deposits at June 30, 2015 increased primarily due to the Merger which added $722.3 million in deposits.
Overall, our customer deposits, which exclude brokered deposits, increased by $789.9 million from December 31, 2014. This increase consisted of $657.2 million from the Merger and $132.7 million of organic growth. Brokered deposits consist of CDs, money market, and interest-bearing demand funds and are an additional source of funds utilized by ALCO as a way to diversify funding sources, as well as manage our funding costs and structure. The increase of $160.7 million of brokered deposits included $65.2 million from the Merger.

Borrowings are an additional source of funding for us. Total borrowings increased by $55.4 million from December 31, 2014. The increase in total borrowings was a result of a new variable rate long-term borrowing of $100.0 million during the second quarter offset by decreases in short-term borrowings of $59.0 million. The increase in borrowings was primarily due to funding needs to support our asset growth. On March 5, 2015, we paid off $8.5 million and on June 18, 2015, we paid off the remaining $5.0 million of the $13.5 million junior subordinated debt that we assumed in the Merger.

Liquidity and Capital Resources
Liquidity is defined as a financial institution’s ability to meet its cash and collateral obligations at a reasonable cost. This includes the ability to satisfy the financial needs of depositors who want to withdraw funds or of borrowers needing to access funds to meet their credit needs. In order to manage liquidity risk our Board of Directors has delegated authority to the ALCO for formulation, implementation and oversight of liquidity risk management for S&T. ALCO’s goal is to maintain adequate levels of liquidity at a reasonable cost to meet funding needs in both a normal operating environment and for potential liquidity stress events. ALCO monitors and manages liquidity through various ratios, reviewing cash flow projections, performing stress tests and by having a detailed contingency funding plan. ALCO policy guidelines define graduated risk tolerance levels. If our liquidity position moves to a level that has been defined as high risk, specific actions are required, such as increased monitoring or the development of an action plan to reduce the risk position.
Our primary funding and liquidity source is a stable customer deposit base. We believe S&T has the ability to retain existing and attract new deposits, mitigating any funding dependency on other more volatile sources. Refer to the Deposits Section of Item 2, MD&A, for additional discussion on deposits. Although deposits are the primary source of funds, we have identified various funding sources that can be used as part of our normal funding program when either a structure or cost efficiency has been identified. Additional funding sources available to S&T include borrowing availability at the FHLB of Pittsburgh, Federal Funds lines with other financial institutions, and access to the brokered deposit market.

An important component of S&T’s ability to effectively respond to potential liquidity stress events is maintaining a cushion of highly liquid assets. Highly liquid assets are those that can be converted to cash quickly, with little or no loss in value, to meet financial obligations. ALCO policy guidelines define a ratio of highly liquid assets to total assets by graduated risk tolerance levels of minimal, moderate and high. At June 30, 2015 S&T had $422.6 million in highly liquid assets, which consisted of $82.9 million in interest-bearing deposits with banks, $326.0 million in unpledged securities and $13.6 million in loans held for sale. The highly liquid assets to total assets resulted in an asset liquidity ratio of 6.9 percent at June 30, 2015. Also, at June 30, 2015, S&T had a remaining borrowing availability of $1.4 billion with the FHLB of Pittsburgh. Refer to Note 9 Borrowings, and the Borrowing section of Item 2, MD&A, for more details.

When comparing June 30, 2015 to December 31, 2014, the capital ratios were impacted by the Merger and new regulatory requirements under Basel III. The Merger between S&T and Integrity closed on March 4, 2015. The new regulatory requirements were effective January 1, 2015 with a phase-in period ending January 1, 2019. The new regulatory requirements include a common equity tier 1 to risk-weighted assets ratio and increased the capital required for certain categories of assets. S&T and S&T Bank continue to be well-capitalized under the new regulatory guidelines.
In October 2012, we filed a shelf registration statement on Form S-3 under the Securities Act of 1933 as amended, with the SEC, for the issuance of up to $300 million of a variety of securities including debt and capital securities, preferred and common stock and warrants. We may use the proceeds from the sale of securities for general corporate purposes, which could include investments at the holding company level, investing in, or extending credit to subsidiaries, possible acquisitions and stock repurchases. As of June 30, 2015 we had not issued any securities pursuant to the shelf registration statement.
Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Market risk is defined as the degree to which changes in interest rates, foreign exchange rates, commodity prices or equity prices can adversely affect a financial institution’s earnings or capital. For most financial institutions, including S&T, market risk primarily reflects exposures to changes in interest rates. Interest rate fluctuations affect earnings by changing net interest income and other interest-sensitive income and expense levels. Interest rate changes affect capital by changing the net present value of a bank’s future cash flows, and the cash flows themselves, as rates change. Accepting this risk is a normal part of banking and can be an important source of profitability and shareholder value. However, excessive interest rate risk can threaten a bank’s earnings, capital, liquidity and solvency. Our sensitivity to changes in interest rate movements is continually monitored by ALCO. ALCO monitors and manages market risk through rate shock analyses, economic value of equity, or EVE, analysis and by performing stress tests in order to mitigate earnings and market value fluctuations due to changes in interest rates.

Rate shock analyses results are compared to a base case to provide an estimate of the impact that market rate changes may have on 12 months of pretax net interest income. The base case and rate shock analyses are performed on a static balance sheet. A static balance sheet is a no growth balance sheet in which all maturing and/or repricing cash flows are reinvested in the same product at the existing product spread. Rate shock analyses assume an immediate parallel shift in market interest rates and also include management assumptions regarding the impact of interest rate changes on non-maturity deposit products (noninterest-bearing demand, interest-bearing demand, money market and savings) and changes in the prepayment behavior of fixed rate loans and securities with optionality. S&T policy guidelines limit the change in pretax net interest income over a 12 month horizon using rate shocks of +/- 300 basis points. Policy guidelines define the percent change in pretax net interest income by graduated risk tolerance levels of minimal, moderate and high. We have temporarily suspended the -200 and -300 basis point rate shock analyses. Due to the low interest rate environment, we believe the impact to net interest income when evaluating the -200 and -300 basis point rate shock scenarios does not provide meaningful insight into our interest rate risk position.
In order to monitor interest rate risk beyond the 12 month time horizon of rate shocks, we also perform EVE analysis. EVE represents the present value of all asset cash flows minus the present value of all liability cash flows. EVE rate change results are compared to a base case to determine the impact that market rate changes may have on our EVE. As with rate shock analysis, EVE incorporates management assumptions regarding prepayment behavior of fixed rate loans and securities with optionality and the behavior and value of non-maturity deposit products. S&T policy guidelines limit the change in EVE given changes in rates of +/- 300 basis points. Policy guidelines define the percent change in EVE by graduated risk tolerance levels of minimal, moderate and high. We have also temporarily suspended the EVE -200 and -300 basis point scenarios due to the low interest rate environment.
The table below reflects the rate shock analyses and EVE analysis results. Both are in the minimal risk tolerance level.

The results from the rate shock analyses are consistent with having an asset sensitive balance sheet. Having an asset sensitive balance sheet means more assets than liabilities will reprice during the measured time frames. The implications of an asset sensitive balance sheet will differ depending upon the change in market interest rates. For example, with an asset sensitive balance sheet in a declining interest rate environment, more assets than liabilities will decrease in rate. This situation could result in a decrease in net interest income and operating income. Conversely, with an asset sensitive balance sheet in a rising interest rate environment, more assets than liabilities will increase in rate. This situation could result in an increase in net interest income and operating income. As measured by rate shock analyses, an increase in interest rates would have a positive impact on pretax net interest income.
The percent change in pretax net interest income increased for our rates up shock scenarios and decreased in the rates down shock scenario when comparing June 30, 2015 to December 31, 2014. This is mainly a result of an increase in our asset sensitive position when compared to December 2014. Our balance sheet became more asset sensitive mainly as a result of an increase in our variable rate loan portfolio.
When comparing the EVE results for June 30, 2015 to December 31, 2014 the percent change to EVE has improved in the rates up and the rates down shock scenario. The improvement is mainly attributed to an increase in our core deposits. The value of core deposits as low cost funding modestly improved our rates down EVE results and provided a larger benefit in our rates up scenarios.
In addition to rate shocks analysis and EVE analysis, we perform a market risk stress test at least annually. The market risk stress test includes sensitivity analyses and simulations. Sensitivity analyses are performed to help us identify which model assumptions cause the greatest impact on pretax net interest income. Sensitivity analyses may include changing prepayment behavior of fixed rate loans and securities with optionality and the impact of interest rate changes on non-maturity deposit products. Simulation analyses may include the potential impact of rate shocks other than the policy guidelines of +/- 300 basis points, yield curve shape changes, significant balance mix changes and various growth scenarios. Simulations indicate that an increase in rates, particularly if the yield curve steepens, will most likely result in an improvement in pretax net interest income. We realize that some of the benefit reflected in our scenarios may be offset by a change in the competitive environment and a change in product preference by our customers.
